One-pot preparation of novel asymmetric structure nanoparticles and its application in catalysis

One-pot method has been applied to the synthesis of new Janus structure nanorods, in which Au nanoparticles are located at one end of mesoporous silica rods. Janus nanorods are synthesized directly by the chloroauric acid solution, without prior preparation of gold or silica nanoparticles. This method is easy and cost-effective for high yield preparation of Janus nanoparticles catalyst. Meanwhile, new Janus nanoparticles have high catalytic activity. Therefore, these new nanoparticles will have broad prospects in catalysis, drug delivery, self-propelled nanodevices, etc.
